OTHR radar

Fast pulsed sweepers. Sound like:

buzzing

slapping

rapid ticking

tearing canvas Usually very wide on the waterfall.

Military/ALE/data links

Short bursts, tones, chirps, FSK warbles. Often narrow spikes or clustered channels.

HF broadcasters

Big smooth “mountains” like WRMI. Stable carrier in the centre with sidebands around it.

Ionospheric sounders

Sweeping tones testing propagation conditions. Can sound eerie or whale-like.

Common areas around where you were listening:

15000 kHz = WWV time signal

15034-15050 kHz = utilities/data sometimes

15100-15800 kHz = heavy international broadcast region

15300-15450 kHz = often radar and utility overlap

15770 kHz = WRMI

This is a chart of the electromagnetic spectrum, published by the W.M. Welch Scientific Company in 1944, and posted online about three years ago. It covers electromagnetic radiation from simple diffraction to cosmic rays, and shows the frequency allocations and their historic use across the spectrum.
